今天给大家介绍一篇中考同源阅读，讲的是海南环岛天然气管网：中国首个环岛天然气管道网络累计输气超350亿立方米，覆盖14个市县、服务超千万人。文章属自然环境与低碳环保、能源转型主题，约194词，蓝思值820L，难度定位初中B2，整体偏AB层，基础班可整篇用作周测阅读，提高班可借词义猜测题拉开区分度。已配好5道阅读题、10空完形填空和中考超纲词预习单，拿来即用。
语篇分析
【What】 海南宣布中国首个环岛天然气管道网络自投用以来累计输气超350亿立方米。这条899公里管网穿过14个市县，服务超1000万人，主要向电厂、工厂和居民供气，替代大量煤炭，据国家管网集团称已减少超2540万吨粉尘和超5120万吨二氧化碳排放。海南还计划2030年停售新燃油车，2025年底清洁能源占发电装机容量87.2%，2030年前碳达峰、2045年建成低碳岛、2060年碳中和。
【Why】 本文落在课标“人与自然”主题语境下的低碳环保与能源转型，真正要证明的一点是：一个岛屿的能源结构可以从煤转向天然气、可再生能源与核能，并用具体减排数字支撑转型成效。后文主旨与推断题会踩的支点，是“环岛管网”这一基础设施如何把清洁能源送到电厂、工厂和千家万户，以及海南给出的一系列时间节点所体现的长期承诺。
【How】 体裁为新闻说明文，段间呈递进逻辑：首段报管网规模与覆盖，第二段用“替代煤炭”和减排数字说明当下成效，第三段用“not stopping there”转入未来目标。数字、人物身份与对比处容易成为细节干扰，如350亿立方米、899公里、14个市县、1000万人、2540万吨粉尘与5120万吨二氧化碳，以及2030、2045、2060三个年份，阅读时需分清哪项属于已发生、哪项属于计划。
Cleaner Energy for a Green Island: Hainan's Natural Gas Network Hits a Big Milestone
Hainan, a beautiful island province in southern China, is working hard to become a low-carbon island. On Wednesday, a big step forward was announced. The country's first island-loop(环线) natural gas pipeline(管道) network has now sent more than 35 billion cubic meters of gas since it started working. This 899-kilometer network passes through 14 cities and counties(县) and serves more than 10 million people.
The network mainly brings gas to power plants, factories, and homes. This clean gas has replaced a lot of coal. According to PipeChina, it has helped cut over 25.4 million tonnes(吨) of dust and more than 51.2 million tonnes of carbon dioxide. Hainan is also making its roads greener. The province plans to stop selling new fuel-powered cars by 2030. It wants all new public and private vehicles to use clean energy.
Hainan is not stopping there. By the end of 2025, clean energy made up 87.2% of the province's power capacity(装机容量). The island is using more renewable(可再生的) energy and nuclear power. Looking ahead, Hainan aims to reach its highest carbon emissions(排放) before 2030. It hopes to become a fully built low-carbon island by 2045 and reach carbon neutrality(中和) by 2060. These plans show Hainan's strong commitment to a greener future.

这组题为什么这样设计？
这组阅读把五技拆到不同段落：首段铺具体信息，中段收主旨，末段留推断与态度，词义线索藏在数字与对比里，老师拿去组卷可一次覆盖细节、主旨、推断、态度、词义五项能力。
整篇命题沿新闻说明文的递进结构布点，细节题盯数字与身份的精确对应，主旨题防例证越位，推断题卡直说与未知的边界，态度题看评价语言，词义线索则藏在数字对比与指代中。真正要测的是学生能否在真实语篇里分清已发生与计划、数据归属与时间先后，这正是中考超纲词与长句并存时最易失分的能力缺口。老师按自然环境与能源转型主题组卷，覆盖面稳、干扰设计有据，用着放心。

本篇文章完型填空的命题特点
开篇以海南低碳岛建设与环岛天然气管道网络为背景，句内语块与语法约束层设置时间状语从句与固定表达，要求根据主句现在完成时判断从属连词，并利用 from A to B 式升降证据确认方向性副词。转折段围绕管网功能与减排成效展开，句际逻辑层通过替代关系与受益对象设空，须区分动作主体与承受者，近义方向层则用服务、覆盖、连接等动词检验搭配范围与宾语匹配。收束段转入未来目标，跨句复现与情感主题层借助 not stopping there 的递进信号、时间节点与承诺类名词，要求从数据与政策中提炼一致基调。整体设计不依赖单句语法成立，而让学生在多处证据协调下恢复被删信息，能测出语篇约束下的信息恢复能力。
本篇文章完型填空的命题特点还在于暴露学生空上看选项、近义方向不核对数据、把搭配当充分条件等缺口。教师将其与同源阅读配套印发，可借助同一语篇的阅读与完形双通道，检验学生能否在语篇约束下恢复信息，而非停留在单句语法填空层面。
文章中文翻译
更清洁的能源，更绿色的岛屿：海南天然气管网迎来重要里程碑
海南是中国南方一个美丽的岛屿省份，正在努力建设成为低碳岛。周三，一项重大进展被宣布。中国首个环岛天然气管道网络自运行以来，已累计输送超过350亿立方米的天然气。这条全长899公里的管网穿过14个市县，服务超过1000万人。
该管网主要向电厂、工厂和居民家庭供气。这种清洁天然气替代了大量煤炭。据国家管网集团称，它已帮助减少超过2540万吨粉尘和超过5120万吨二氧化碳排放。海南也在让其道路交通更加绿色。该省计划到2030年停止销售新的燃油汽车。它希望所有新增公共和私人车辆都使用清洁能源。
海南并未止步于此。到2025年底，清洁能源占该省发电装机容量的87.2%。该岛正在使用更多可再生能源和核能。展望未来，海南的目标是在2030年前达到碳排放峰值。它希望到2045年全面建成低碳岛，并在2060年实现碳中和。这些计划显示了海南对更绿色未来的坚定承诺。

超纲词名师点评
我是许乃夫老师，前新东方功勋教师，教了二十多年英语，最怕看到学生把单词背成一张张孤立的卡片。这篇海南环岛管网的阅读，真正值得在班上停下来讲的，我选 pipeline、capacity、renewable、emission、neutrality 这几个。它们不是最难的，却是本文信息链条上的关节。
先看 pipeline。学生看到 pipe 就想到“管子”，但本文的 pipeline 是那条 899 公里的 network，是基础设施，不是一根水管。第一段说 the country's first island-loop natural gas pipeline network has now sent more than 35 billion cubic meters of gas，这里的 pipeline 和 network 合在一起，才构成“环岛管网”这个概念。如果只译成“管道”，学生容易漏掉“成网、覆盖 14 个市县、服务超 1000 万人”这层规模感，而规模感恰恰是后文减排数字可信度的来源。
再看 capacity 和 renewable。第三段 clean energy made up 87.2% of the province's power capacity，capacity 在这里不是“能力”，是“装机容量”，是电力系统里一个很具体的量。学生若按“能力”去理解，整句话会变成“清洁能源占了能力的 87.2%”，逻辑就飘了。紧接着 renewable 出现，the island is using more renewable energy and nuclear power，renewable 作形容词是“可再生的”，但这里和 nuclear 并列，其实是在说能源结构的两大块。这两个词放一起，学生才能看懂海南不是只靠天然气，而是在铺一张更宽的能源网。
emission 和 neutrality 是本文的时间轴落点。emission 在 carbon emissions 里是“排放”，学生常见的是动词 emit，名词形式反而反应慢；neutrality 更典型，词典给“中立”，可 carbon neutrality 是“碳中和”，不是政治中立。这两个词如果只背中文释义，学生读到 Hainan aims to reach its highest carbon emissions before 2030 和 reach carbon neutrality by 2060 时，很难把“达峰”和“中和”两个阶段连起来。我会让学生回到句子里，把 before 2030 和 by 2060 这两个时间点圈出来，词义自然就站稳了。
老师用这份词表时，不必逐词领读。可以先让学生在原文里找出 pipeline、capacity、renewable、emission、neutrality 所在句子，用上下文猜一遍，再对照词表验证。学生要做的，是在句子里确认词义，而不是在词表里背序号。配套的单词小超市里，本篇预习单和语境跟读音频可以让学生把这几句再听一遍、读一遍，词在声音和上下文里多滚几次，阅读反应才会真的快起来。
